|As it is supposed to be high,so o4 to o6 ia the best range,the SPC also uses from o4 to o6.The vibrato parameters I've used for the p command were p10,40 and p10,48.The fast trill ADSR is for shorter trills.I also used $F4$10.
This is a actually a "pack" of various ADSR parameters to use for High notes on @4.
The Trill Violin is just a variation to make the volume increase
smoothly as if increasing the strength of the bow.I also recommend using $F4$01 for the trills,cause even with high attack,it doesn't sound natural,the trill may sound weird with $F4$01 in 4th octave,so using the Attack Violin is better.
In the lowest notes of 4th octave,I would recommend using the Attack Violin instead of Soft Violin.
